6. The method of claim 1 , wherein determining a first acoustically-effective room volume estimate comprises modeling an open door in the first room as a closed door.

7. The method of claim 6 , wherein modeling the open door as a closed door comprises ignoring a volume of the second room.

8. A non-transitory program storage device comprising instructions stored thereon to cause one or more programmable control devices to: obtain a first one or more room parameters for a first room; determine a first acoustically-agnostic room volume estimate for the first room using the obtained first one or more room parameters; determine a first acoustically-effective room volume estimate for the first room based on the first acoustically-agnostic room volume estimate and one or more acoustically-relevant room features in the first room; and generate an audio signal based, at least in part, on the determined first acoustically-effective room volume estimate, wherein the first acoustically-effective room volume estimate is a different volume than the first acoustically-agnostic room volume estimate, and wherein at least one of the acoustically-relevant room features comprise at least one of: an open space; a half-open open space; a convoluted space; one or more holes; or one or more acoustically unreachable corners.

9. The non-transitory program storage device of claim 8 , wherein the first one or more room parameters comprise a 3D room model for the first room.

11. The non-transitory program storage device of claim 8 , wherein one or more acoustically unreachable corners of the first room comprise at least one of the following: a corner region of the first room; a region behind a piece of furniture in the first room; and a region of the first room that is unreachable by acoustic rays emanating from a sound source in the first room.

12. The non-transitory program storage device of claim 8 , wherein instructions to determine a first acoustically-effective room volume estimate further comprise instructions to model an open window in the first room as a closed window.

13. The non-transitory program storage device of claim 8 , wherein instructions to determine a first acoustically-effective room volume estimate further comprise instructions to model an open door in the first room as a closed door.

14. The non-transitory program storage device of claim 13 , wherein instructions to model the open door as a closed door further comprise instructions to ignore a volume of the second room.

15. An electronic device, comprising: memory; audio output circuitry; and one or more programmable control devices coupled to the memory and the audio output circuitry, the one or more programmable control devices being configured to execute instructions stored in the memory to cause the one or more programmable control devices to: obtain a first one or more room parameters for a first room; determine a first acoustically-agnostic room volume estimate for the first room using the obtained first one or more room parameters; determine a first acoustically-effective room volume estimate for the first room based on the first acoustically-agnostic room volume estimate and one or more acoustically-relevant room features in the first room; and generate an audio signal based, at least in part, on the determined first acoustically-effective room volume estimate, wherein the first acoustically-effective room volume estimate is a different volume than the first acoustically-agnostic room volume estimate, and wherein at least one of the acoustically-relevant room features comprise at least one of: an open space; a half-open open space; a convoluted space; one or more holes; or one or more acoustically unreachable corners.
